To make my transition, these were the apps I used/tried:
1. I liked iPhone's screen dimming before completely blanking out. I used to hit the touch-screen whenever it dims if I want to keep the screen on for reading a long email/article. I did not find that as an option on Android OS... so I tried the app: Screebl - this app keeps the screen on based on the orientation and does exactly what I was looking for. [then I looked if such an app existed for iOS, but could not find].
2. Music
This will continue. [should be on it's own blog].
